Zeuzerid larva.— Mr. A. Bacot, a large Zeuzerid larva of an 
unknown species from Australia. 
Paper. — Mr. A. Bacot read a paper, entitled “ Notes on Arctiid 
larvae.” The special line to which attention was given was the dis¬ 
position and nature of the tubercles. These were extremely difficult 
organs to deal with, as they were apt to lead one away from true 
relationship. Thus Arctiadae, Noctuidae, and the butterflies became 
somewhat closely connected upon a study solely of the tubercles, while 
the atrophy of the primary tubercles made the Arctiids like the 
Sphingids in that respect. Arctiid larvae offered no constant 
characters that could be taken independently for classification. The 
Arctiadae were well separated as a family by the oval characters. The 
eggs were always sculptured with delicate pittings, and certain larval 
characters might be taken in support of this basis, but there were 
many larval characters to choose from. Syntomis phegea placed the 
egg differently from the majority of Arctiids, and more like the 
Zygaenids, illustrating a parallel in habits and habitat. It was 
interesting to note that all Arctiids hybernated as larvae, but hyberna¬ 
tion was an unstable character in classification. Mr. Bacot closed his 
paper with a rough scheme for separating certain isolated members or 
groups. Thus Spilosoma offered certain differences, while Euchelia 
jacobaeae was quite isolated by its larva bearing single hairs instead of 
bunches of hair on the setae. At the finish of the paper Mr. A. W. 
Mera proposed a vote of thanks, and alluded to the curious hybernating 
differences in otherwise very closely related species, and alluded to 
Orgyia gonostigma , that hybernated as a larva, whilst its very near 
relative, <>. anti qua, passed the winter in the egg state. Mr. W. J. 
Kaye seconded the vote of thanks. Mr. L. B. Prout, Mr. Alfred Sich, 
and Dr. T. A. Chapman also spoke in support of the vote, and the last 
mentioned made some remarks on the glandular hairs of the larva, 
saying that in some species all the hairs were glandular, while in 
others only some were so constructed. 
March 1st, 1904. — New Member. — Mr. R. G. Benton, of Water- 
burg, Wood Lane, Highgate, was elected a member of the Society. 
Eupithecia minutata var. knautiata. • — Mr. Y. Eric Shaw, 
Bu/dthecia minutata var. knautiata, bred from Bury, Lancashire. 
Arctia caja aberrations. — Mr. C. P. Pickett, two fine aberrations 
of Arctia caja, one of which had dark brown antennae, instead of the 
usual pale colour. 
Bred Sesia fuciformis and JUgerta apiformis, etc. — Mr. A. W. 
Mera, Sesia fitciformi; s and Aegeria apiformis, with many of the fugitive 
scales adhering. He stated that the least flutter was sufficient to 
cause the insect to loose these scales. Mr. W. J. Kaye, a large number 
of insects with transparent wings, or with partially transparent wings, 
including many species from S. America of the families Syntomidae, 
Arctiadae, Aegeriadae, Erycinidae, Hypsidae, Geometridae , and Hes- 
periadae. 
Paper.- — Mr. W. J. Kaye read a paper on “ Transparency in Lepi- 
dopterous wings ” {vide Ent. Bee., vov. xvii., pp. 83-8(3 et seq.). Refer¬ 
ence was first made to the well-known British species, Sesia fuciformis 
and Sesia bombyliformis, and the Aegeriid species, but it was stated that 
it was in S. America where the phenomenon of transparency had been
